19 Years Old and Already Acting Like He Owns the Shortstop: Konnor Griffin's Maturity Is Turning Heads in Pittsburgh

When Konnor Griffin stepped into the box against Mason Miller last week, the 19-year-old Pirates rookie got the welcome-to-the-majors moment he won't forget. Miller, the star closer for San Diego, came at him with triple-digit fastballs and nasty sliders. Griffin struck out on five pitches, three of them over 100 mph, finishing with a slider that was a different animal from anything he'd faced before. But here's the thing: the kid didn't pout. He didn't make excuses. In just his sixth career game, Griffin handled it like a veteran.

"That was a tough at-bat, but that was a great experience," Griffin told ESPN after the at-bat. "There's not many closers that are better than that. It was good for me to jot something down on the notepad and learn from it for the next time." He came away unbothered. "Now, I've done it. I have info I can use to my advantage."

A Teenager With a 35-Year-Old Brain

If Griffin sounds more mature than most 19-year-olds, that's because he is. The Pirates put serious faith in him by making him the starting shortstop and handing him a nine-year, $140 million contract before he'd played an inning in the big leagues. That's a massive bet on a kid who's still technically a teenager. But his teammates aren't seeing a kid fumbling his way through the majors. They're seeing someone who has it together.

"It's definitely different being young, but we all have the same jobs," Griffin said. "When you have that common goal, it doesn't matter your age or experience; it's about getting the job done."

Veteran Bryan Reynolds, 31, couldn't point to anything that screams "teenager" about Griffin. Not his music taste, not his food orders, not even his video game habits. "There's nothing that's happened where I'm like, 'That's just a kid,'" Reynolds said. "He has his life together." Outfielder Jake Mangum laughed about graduating from the same high school a decade apart. "When he walks up to the plate, and they show his date of birth as 2006, it's just like, 'Oh my gosh,'" Mangum said.

Even the Cy Young Winner Noticed

Even reigning National League Cy Young winner Paul Skenes found something endearing about Griffin's actual youth. Skenes noted that Griffin worried about how his teammates would feel after he signed that massive contract before playing a single inning. "That's something that other people wouldn't be worried about," Skenes said with a smile. "Everyone realizes it's part of the game. That question was kind of funny. That's a reminder that he hasn't been here."

Still, Skenes admitted that kind of concern could actually be viewed as mature. This kid is handling pressure and expectations the way veterans do. That's the real story in Pittsburgh right now.
